Here are some things to consider about plants in light of your arguments:
1. 99% of all plants on Earth are toxic to human beings -- this is in comparison to 99% of all animals on Earth being safe for human beings to eat (including venomous snakes).
2. The fact that plants cannot move means that they fight off predators with toxins and chemicals. They contain natural pesticides, for instance. The only part of the plant that it wants to have eaten is the fruit. The seeds, on the other hand, are particularly well-defended. Plants contain lectins, oxalates, tannins, glucosinolates, and the list goes on and on. Animals don't fight back once they are dead, but plants do. (This is why 99% of plants are toxic to humans).
3. Plants have regular seasons, as you mentioned -- which is why plants are not available to be eaten through the winter in many parts of the world. Somehow our ancestors not only survived winters but also ice ages. Animals, on the other hand, exist year-round.
4. Hunting is not necessarily a risky exercise -- the largest animals, which provide the most calories, do not tend to run. Animals like Elephants, Rhinos, Hippos, etc., will turn and face a predator. They also have predictable paths to watering holes and can easily be captured by digging a hole in the ground and covering it with leaves.
You've made a good attempt at coming up with arguments, but I'm afraid the weight of the evidence argues in favor of our ancestors consuming mostly animals. In fact, the acidity of our stomachs is extremely high, in line with vultures, and is what we would expect to find in "hyper carnivores".

I've gone as deep as two years full carnivore. The literature and pseudoscience is quite familiar.

That was a critique, not an argument. I was trying to show handwaving without reputable citations is not an argument at all. It's just a narrative based on assumptions, unverified trust. You cite Times Of Israel, I could point to vegan/omnivore articles in HuffPo or Buzzfeed. Neither would have substance. Here is an example of an argument: https://biology.stackexchange.com/a/55977
